ZSHEETS-SHEET Z 'INVENT'01:-

cone 41, its outer bevel is parallel to thebeveled inside portion of the outer casing 9 at the passage 22.

By screwing in or out the sleeve 40, the narrow oil passage43 and the wide air passage 22 are closed or opened as desired.

The light metal band 44 fastened to the top of cylinder 9 and passing over the flange415 of the sleeve 40 and around the pipe 1, as shown on Figs. 1 and 2, serves as a stop for the sleeve 40in screwing it out of the cylin 1st-The novel construction of the inner.

pipe 1 Fig. 1 and of. the conformingly shaped portion of the surrounding outer cylinder 9, namely: the lower part 23-of the inner pipe 1, as here shown, being made cylindrical instead of conical,with projecting saw-teeth shaped ribs on the outside, with its bottom fastened to the bottom 416 of thepedestal 23, and having several square holes on its outer surface carrying the sockets or valves 31.

2d--The lower half of the surrounding outer cylinder 9, instead of being conical, is here made cylindrical all through on its outside, with a projecting curved portion and with saw-teeth shaped ribs on its inside, with its bottom screwed on to the top faucet 17 of the pedestal 23, and having its air inlet openings 11 enclosed between the two flanges or rings 10 cast on its outside surface. and clamped fast to the hollow piston 2 of the surrounding air-circulation starting device. The projecting curved portion inside the outer cylinder 9 at the passage 22 may be made either solid, as shown on Fig. 1, or it may be reduced in size, or entirely omitted, and the clearance space filled up with some light absorbent porous fabric, as shown on Fig. 6, according to the volatility of the oil used and its capillary aflinity for diffusion with air.

The saw-teeth shaped ribs providedin the lowerpart of the passage 22 are for subjecting both streams-the air and the oil-to a zig-zag inter-mingling with each other.

The above mentioned air-circulation starting device consists of the hollow piston 2 with the attachedcover 3, both having air inlet ports 12 and rubber flaps or rings 5 and 6, held in placeby means of the light ferrules 8 passing through the hubs of the piston and cover 2 and 3 and flanged over.

These ferrules 8 are fitted-to the'outer cylinder 9, and together with the hubs and rubber flaps are clamped fast to the flanges or rings 10 of the outer cylinder 9 by the piston 2 and its cover 3 bolted together.

Thus, the hollow piston 2 surrounding the airinlets 11 to the central mixing and proportioning valve forms one stationary bod with the same.

The air inlets 11 and 12 are shown in plan on Fig. 3.

The stationary piston 2 is surrounded by the movable cylinder 13 Fig. 1 with its two covers 14 and 15, both provided with the air inletports 16, the rubber flaps or rings 4 and 7 and the ferrules 17 and 18 slidingly titted around the outer cylinder 9 and flanged over the hubs of the covers and over the rubber flaps, as shown.

. The air inlet ports 16 are shown in plan on Fig. 2, with the cover plate 19 removed. This cover plate 19 is supported by the ribs 20, Figs. 1 and 2, cast on top of the cover 14 and is held in place by the ferrules 18 flanged over it, the outside air having free access to the air inlet ports 16 through the circumferential clearance between the'cover plate 19 and the cover 14:.

The movable outer cylinder 13 is held. up in its upward position shown by the spring 21, located inside the movable cylinder 13 and pressing against the piston 2 at one end and the cover 14- at its other end.

The action of the circulation starter is as follows: Normally, when in working condition, with the combustion mixture ignited and air and oil circulating freely, the rubber flaps 1, 5, 6 and 7 are in a horizontal position as shown on Fig. 1, and the outside air passes freely through all the ports of the movable cylinder and those of the stationary piston into the interior of the mixing and proportioning valve.

When not in working condition, then, in order to start circulation just before ignition, the movable cylinder 13 of the circulation-starter is pressed down; the air in its upper half becomes compressed, the rubber flaps 41 and 6 close the adjacent ports, the flaps 5 and 7 open fully, and the air from the upper half of the cylinder 13 is forced through the ports 11 into the interior of the mixing and proportioning valve, while the lower half of cylinder 13 fills up with air.

Release-d, the cylinder 13 is lifted up by the spring 21; the air in its lower half becomes now compressed, the flaps 5 and 7 close the adjacentports, the flaps 4.- and 6 open fully, and the air from the lower half of cylinder 13 is forced through the ports 11 into the mixing and proportioning valve.

Thus, a few strokes of cylinder 13 forces a continuous current of air and of entrained oil with it through the zigzagged passage 22 of the mixing valve up to the ultimate exit where it is ignited with a match and a normal draft established.

On either end of the piston 2, close to the ferrules 8, are the rubber rings 0 to take up the shocks. e

In its ensemble, as a complete working unit, the wickless oil-lighting and heating appliance comprises the central mixing valve organically combined with the circulationstarter and with the pedestal. I

The pedestal consists of the hollow base or frame 23 with the well or pocket 24 in the centre with the tapped faucet 47 on top. From the well 24 several radial channels 25 branch out, terminating in the tapped sockets 26 on topof the legs 27, as shown on Figs. 1 and 4.

Into the top faucet 47 of the pedestal 23 is screwed the bottom end of the outer cylinder 9, while to the bottom 46 of the well is fastened the bottom end of the hollow cylindrical portion 28 of the inner pipe .1 of the mixing valve, by means of the two tap bolts 29 with the locking washer 30, as shown on Figz l. p

The hollow cylindrical portion 28 has on its surface several square holes, just opposite the entrance to the channels 25, carrying the sockets or valves 31, which are thus pre vented from turning, but can move freely in or out of these square holes.

These sockets are tapped inside and hold the threaded ends of the rods 32, located inside the channels 25. The other end of these rods pass through the legs 27 and have the hand knobs 33 fastened to them, as shown on Figs. 1, 4 and 5. 38 is a metal or rubber filler ring, closing up the outer end of the channels 25.

To prevent the rods 32 from moving lengthwise they are provided with a circu lar notch, with the two set screws 34 abutting against it, as shown on Figs. 4 and 5.

Thus, by turning the handles 33 with the rods 32 to the right, the sockets 31 will be pulled out towards the rods, closing the channel entrances to the Well 24, as is shown on the left side of Fig. 1 reversedly, by turning the handles 33 with the rods 32 to the left, the sockets 31 will be pushed away from the rods, and the channel entrances to the well 24 will be opened, as is shown on the right side of Fig. 1.

In this way the combustion mixture from the mixing valve can be supplied to any one of the terminal sockets 26, or out off, as desired.

The-bottom of the pedestal 23 is closed up by the plate 35 fastened to the bottom flange of the pedestal, thus forming a large closed space communicating with the interior of the well 24 by the small holes 36 in the well bottom, as shown on Fig. 1.

Should any oil dripping occur while the apparatus is not working and the oil pas sage 43' left unclosed, it will thuscollect in that closed space and can be at any time drained off through the plugged up hole at 37, provided in one of the legs 27, as shown on Fig. 1'. v 1

On Fig. 7, Sheet 2 myjwickless oil-lighting andheating appliance shown in ensemble, as utilized for lighting purposes, with two of the terminal sockets connected to closed high temperature lighting burners, described in my patent applications Ser. #439,453 and #442,432.

On the left is shown an auxiliary mixing and proportioning valve, described in previously mentioned" patent application Ser. #412,736, introduced for the" purpose of the final right proporti'onin'g of oil with air.

The other sockets may likewise simultaneously be connected to any other kind of lighting or heating burner, and there; be as many connecting'branclie's provided inthe' pedestal as desired.

The oil reservoir 39 is here shown at tached direct to the top of the central mixing. valve with a cock between but it may as well be located anywhere convenient-1 y.

The advantages of my wickless oil-lighting and heating appliance over other methods of kerosene oil lighting and heating now existing are:

1The air in my appliance automatically takes the place of the common wick as an oil-carrier to the burner.

2-Saving in oil consumption due to perfect combustion through exact mixing and proportioning of oil and air, giving a flame of maximum temperature, transmitting more heat and imparting higher incandescence t0 the mantle.

3Relief from the wick and from the dirt and trouble associated with it.

4Compactness and potability combined with perfect safety,'due to the substantial construction of all parts, and to the separation of the burner proper from the oil container.

What I claim is: r

1. A wickless oil-lighting and heating appliance, comprising an oil and air mixing valve, an air-circulation starter, a pedestal with conveying channels, means for closing and opening the entrances to said channels, gublstantially as and for the purposes speci- 2.
